  packageData={packageData}

## API

<FunctionAPI function={docs.exports.useSeparator} links={docs.links} />

## Features

Horizontal separators can be built with the HTML [&lt;hr&gt;](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/hr)
element. However, there is no HTML element for a vertical separator. `useSeparator` helps achieve
accessible separators that can be styled as needed.

* Support for horizontal and vertical orientation
* Support for HTML `<hr>` element or a custom element type

## Anatomy

A separator consists of a single element that represents the divider.
`useSeparator` returns props to be spread onto the element:

<TypeContext.Provider value={docs.links}>
  <InterfaceType properties={docs.links[docs.exports.useSeparator.return.id].properties} />
</TypeContext.Provider>


## Example

This example shows how create both a horizontal and a vertical oriented separator.

```tsx example
import {useSeparator} from '@react-aria/separator';

function Separator(props) {
  let {separatorProps} = useSeparator(props);

  return (
    <div
      {...separatorProps}
      style={{
        background: 'gray',
        width: props.orientation === 'vertical' ? '1px' : '100%',
        height: props.orientation === 'vertical' ? '100%' : '1px',
        margin: props.orientation === 'vertical' ? '0 5px' : '5px 0'
      }} />
  );
}

<>
  <div style={{display: 'flex', flexDirection: 'column'}}>
    Content above
    <Separator />
    Content below
  </div>

  <div style={{display: 'flex', flexDirection: 'row', marginTop: 20, height: 40, alignItems: 'center'}}>
    Content left
    <Separator orientation="vertical" />
    Content right
  </div>
</>
```
